Cognitive Development Theory - Essay Example This test was adopted to be used in the United States in 1905 by a psychologist called Lewis Terman (Morra, 2008). The intelligent quotient has its scoring concept based on the mental age. In this test, the average intelligence of a child needs to match with his/her age. However, a gifted child has his or her performance compared to that of older children while the slow leaners are identified through comparisons with younger children.
